Embodiment 1

[0046] Components: by mass fraction, sodium percarbonate 0.5%, acetylguanidine 0.125%, add water to 100%.

[0047] Pipette 50mL of the prepared disinfectant into a 100mL three-necked round-bottomed flask, stir at a medium speed for 30min, then transfer 250μL of poison (Viex or Soman) using a micro-injector, and take out 2mL of the disinfectant in 2mL after reacting for 30min. In the extractant (petroleum ether or dichloromethane), shake and shake well, take the extract for toxicant residue analysis, the sample is analyzed by chromatography HP6890-FID. The result is that the disinfection efficiency of Viex and Soman can reach more than 99% within 30 minutes.

Embodiment 2

[0049] Components: by mass fraction, sodium percarbonate 2%, acetylguanidine 2%, synergist 1.2%, add water to 100%.

[0050] Pipette 50mL of the prepared disinfectant into a 100mL three-necked round-bottomed flask, stir rapidly for 30min, then transfer 250μL of poison (mustard gas or Viex) using a micro-injector, react for 5min, take out 1mL of disinfectant and extract it in 2mL Shake well in the solvent (petroleum ether or dichloromethane), and take the extract for toxic agent residue analysis. The mustard gas sample is analyzed by T-135 spectrophotometry, and the Viex sample is analyzed by chromatography HP6890-FID. The result is that the disinfection efficiency of the mustard gas disinfection reaction can reach more than 99% in 5 minutes, and the disinfection efficiency of Viex disinfection reaction in 5 minutes can also reach more than 99%.

Embodiment 3

[0052] Components: by mass fraction, sodium percarbonate 2%, acetylguanidine 2%, synergist 1.2%, add water to 100%.

[0053] Pipette 50mL of the prepared disinfectant solution into a 100mL three-neck round-bottomed flask, stir rapidly in the middle for 30min, use a micro-sampler to pipette 25μL of poison (mustard gas or Viex) into a 25mL stoppered test tube, and then add 5mL The pre-prepared disinfectant solution was shaken and mixed, and it was left to stand for 30 minutes. The residual poison was extracted with the extractant, and the extract was taken for the analysis of the poison residue. FID analysis. The result is that the disinfection rate of the mustard gas droplet standing for 30 minutes can reach 95%; the disinfection rate of Viex standing for 5 minutes can reach more than 99%.

Abstract

The present invention relates to a disinfectant formula based on a hydrogen peroxide activation system. The disinfectant formula comprises a peroxide and an activator, and the activator is a guanidinederivative. The present invention also relates to an application of the above disinfectant formula based on the hydrogen peroxide activation system. A disinfectant provided by the present invention is applied to disinfection of at least one of sarin, soman, mustard gas, and o-ethyl-s-[2-(diisopropylamino) ethyl] methylphosphonothiolate.

Description

technical field [0001] The invention relates to the field of environmental disinfection, in particular to a disinfectant formula and application based on a hydrogen peroxide activation system. Background technique [0002] At present, the main disinfectants are chlorine-containing disinfectants and peroxide disinfectants. Chlorine-containing disinfectants have a series of environmental and ecological pollution problems due to their strong corrosiveness, irritation, toxicity, and residual problems in the application process. Peroxide disinfectants are environmentally friendly disinfectants. During the disinfection process, the substances decomposed by sodium percarbonate are active oxygen, water and sodium carbonate. These products hardly pollute the environment. However, the disinfection performance of hydrogen peroxide to some special poisons is relatively poor, and its application to biochemical warfare agents is greatly restricted. [0003] At present, there is an urgen...
